Now have about 8hrs on a set of NRG 16g. There are a couple notching/fraying in some areas, but still very playable. String movement is a smidge more, but def managable. Great feel and touch, with the pop when needed. I'm planning on trying a stick out with NRG2/RIP Control crosses to see if the RIP locks in and provides a smidge more spin. All in all--this is a very nice string. Tension maintence is excellent for a multi!!!
